Nursery contributed plant descriptions

This is the tall Southern California native Delphinium. It has deep tuberous roots and sends up stems to 6 ft. tall! The tall stalks bear dozens of bright red, long spurred, elf-cap shaped flowers across with yellow throats. Spectacular at the back of flower beds. Unlike the Northern California Delphinium, this one does not flower until late Spring or early Summer. Loves heat - so will do best in our hotter areas in semi-dry gardens. Usually goes somewhat dormant after bloom (so no water then). Well drained soil.
